I just installed the SYE, adjustable control arms and of course the new drive shaft. Drive vibration 95% gone. Tires have a disgruntled tread which causes much of what vibration is left. I will get a different set of sneakers or live with it. I haven't changed the transmission oil yet, but sometimes the 5-speed syncros complain between gears until it warms up. If the new lube does not fix that, I'll probably have to rebuild it to achieve perfection. I am told locally the 5-speeds are the better and more desirable trannys, the junkyards are full of unwanted 6 speeds. Does that ring true?
